SPRING BED-BOTTOM.

SPECIFIGATION formng part of Letters Patent No. 447,133, datecl February 24, 1891. Applica'c-ion filecl March 15 1888. Serial No. 267,207. (1l0 model.)

T0 0ll whom it may concern.-

Be known that I, GEORGE KEENHOLTS, a citizen of the Unted States, resicling at; Philaclelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvernents in SpringBecl- Bottoms, of which the following is a specificatien.

My invention has relation to spring bedbottoms of the form having the springs 'e0n nectetl a'n their upper coils by a coiled wire weaving, lacing, or other similar wie-cloth, so that the upper coils of the springs are flash with the weaving or cloth connecting the same; and it has for its object simplicity and eeonoxny of construction of the bed-bottom as te be susceptible of foldinginto compact form f0r storage, transportation, and other purposes.

My uvention aceordingly consists of the eombination, construction, ancl arrangement of parts, as hereinafter described in the specification, and pointed out in the claims, reference being had to the accornpanying drawings, wherein- Fgure 1 represents a plan of aspring bedbotlzorn having a metal wire clcth 0r webbing interwoven among the top coils of the springs t0 conneet them together and arranged te fold longtudinally in accorclance with my invention; Fig. 2, a sicle elevation of the same; ancl Fig. 3, an end view of the same, showing the bed-bottom foldecl.

A indieates the bed-bottom, composecl of parallel rows of single or other cone-shapecl spiral springs B, the bottoms of which are secured to ametallic base C. Saicl-base censists of the longitudirial metallic straps er slats 6 and the cross straps 0r slats c',and if it is desired to make the bed-bottom in two sections the cross-slats 0 are clivicled s0 as to folcl into the positon shown in Fig. 3.

D indicates the top surface of the bed-bottom, and it is composecl, preferably, of a webbing er weaving of wire, which is interlacecl 01 weven with the top c0ils of the springs to connect them together in any suitable manner, forming an even elastc receptacle for the springs.

The webbing, laengg, 0r wire-cloth D may be com posecl of two longitudinal surfaces 0r sections d d, joinecl 0r hingecl together by interweaving or otherwise connecbing the contacting scles cl of the sections, s0 as te aclrnit of folcling the sections togetl1er, as shown in Fig. 3. The coiled wres composing the lac ing, webbng, or cloth rnay run transversely,

said coils or springs, so that the mattress.

rests upon the interlaced wire fabric and. not

upon the sprngs B, the manclrel-openings of which may be open 0r covered by said wires, as shown in Fig. 1.

'Ihe -webbing er lacing D may be in sections, as shown, Ol otherwise, as desired, te admit of the folcling of the bed-bottom, as clescribed.

I wish it undersizood that I do not herein claim a spring bed-bottom consisting of a flxible metallic base, spiral springs thereon, and a weven-wire top portion, as herenindicatecl, but; which is adaptecl to be rolled instead of folcled, as sucl1 forms the subjectmatter of a separate applicaton filedDecem loer 30, 1890, as a clivision of this application ancl numbered in serial 376,260.

What I claim is A spring bed-bottorn having a base composecl of two sets of longitudinal slats, the slats of each set being unitecl by ransverse slai;s, springs B, secured upon said base-slats, the top of each section composed of parallel courses of wires nterlaced with each obher .and with the t0p coils of the springs, and the
